As shown in Table 3, a far-infrared thermal reflectivity of the fabric is more than 98%; after the fabric is washed 5 times, the reflectivity remains above 98%; and after the fabric is washed 10 times, the reflectivity is 96%, only decreasing by about 2%, indicating that the fabric maintains stable and efficient heat preservation effect.

The prepared heat storage and preservation finishing liquor maintains a particle size of 300 nm-500 nm. As shown in Table 4, after 8 months of storage, components of the finishing liquor remain stably mixed together without settling, and the viscosity is approximately 3.76 mPa.Math.s, with a rate of change of the viscosity being 7.43%; and after 12 months of storage, the finishing liquor begins to settle, and the viscosity is approximately 3.82 mPa.Math.s, with a rate of change of the viscosity being 9.14%. The heat storage and preservation finishing liquor prepared with this formulation exhibits a relatively high viscosity of 3.5 mPa.Math.s-3.82 mPa.Math.s and a large rate of change of the viscosity. Settling occurs after 12 months of storage, indicating poor stability.

Therefore, the heat storage and preservation finishing liquor exhibits relatively poor heat storage and warming effects and stability, as well as a relatively low far infrared thermal reflectivity, but the reflectivity stability remains relatively high.

The heat storage and preservation finishing liquor prepared with this formulation has a relatively low viscosity of 1.31 mPa.Math.s-1.45 mPa.Math.s and a large rate of change of the viscosity. Settling occurs after 8 months of storage, indicating poor stability.

[0032] As shown in Table 8, the fabric achieves heat storage and a temperature rise by 18.2 C. within 20 minutes, indicating poor heat storage and preservation effects worsen than Example 1. After the fabric is washed 10 times, the heat storage and warming performance is reduced less than 2%, indicating good stability of the heat storage and warming effects.

Main effective components of the finishing liquor are the silicon-boron polymer, ceramic nanomaterial, and acidic hot lava material, which have the heat storage and warming functions, and the ceramic nanomaterial also has the function of reflecting thermal radiation. The three components, in appropriate proportions, are grounded and mixed uniformly, and interact with each other to achieve the heat storage and warming functions of the fabric; and the nano-sized effective components are uniformly dispersed in the solution under the action of the cross-linking agent, dispersing agent, and adhesive, and the good dispersion performance ensures that the finishing liquor does not settle after prolonged storage, minimizes slight changes in viscosity, and maintains excellent stability.

[0053] In Example 2, the content of the ceramic nanomaterial is high, with a small particle size and few surface defects, resulting in good adhesion to other components and high strength. In addition, the finishing liquor has a high content of the cross-linking agent and a high total solid content, resulting in an increase in viscosity. In Example 3, the content of the cross-linking agent is too low, resulting in weak interactions among the effective components, causing low viscosity and poor stability of the finishing liquor.

[0054] Analysis of the performance of the finishing liquors in Comparative Examples 1-3 shows that Comparative Example 1, which lacks silicon-boron polymer, exhibits the lower heat storage and warming performance and the worst stability, indicating that the silicon-boron polymer has the greatest impact on the heat storage and warming performance of the fabric. Comparative Example 2, which lacks ceramic nanomaterial, exhibits low far infrared reflectivity and poor heat preservation effects, indicating that the ceramic nanomaterial has the greatest effect on the far infrared reflectivity of the fabric. Comparative Example 3, which lacks acidic hot lava material, exhibits higher far infrared reflectivity and better heat preservation performance than Comparative Example 2; however, after the fabric is washed 10 times, the heat preservation effects decrease by 4.17%, indicating poor stability of heat preservation performance, this reveals that the acidic hot lava material has the greatest effect on the stability of the heat preservation of the fabric. Furthermore, components of the dispersing agent and adhesive in Comparative Examples 1 and 2 are relatively simple, resulting in uneven dispersion of the effective components and poor stability of the finishing liquor. Settling is significant after a prolonged period of storage, leading to a reduction in the content of effective components and an increase in rate of change of the viscosity, which in turn affect the content of effective components in the fabric and ultimately reducing the heat storage, warming and heat preservation performance of the fabric. The absence of any one of the three components adversely affects the dispersibility and stability of the finishing liquor, thus compromising the heat storage, warming and/or heat preservation performance of the fabric.

[0055] For Comparative Examples 4-6, the types and combinations of cross-linking agents, dispersing agents, and adhesives are changed. In Comparative Examples 4 and 6, only the type of dispersing agent is changed, while the amount of dispersing agent remains unchanged, and the cross-linking agent and adhesive also remain unchanged. The resulting finishing liquors begin to settle after 4 months of storage, indicating extremely poor stability of dispersion. Moreover, these finishing liquors exhibit poor heat storage and warming effects and low far infrared reflectivity, the fabrics prepared with these finishing liquors exhibit a decrease of 11.83-14.81% in the heat storage and warming performance and a decrease by 5.32-7.37% in the heat preservation after the fabrics are washed 10 times, indicating poor stability of the heat storage and warming effects and the reflectivity, and poor adhesion of the effective components to the fabric. In Comparative Example 5, the types of cross-linking agent, dispersing agent, and adhesive are changed, while the amount of these components remains unchanged, and the resulting finishing liquor suffers settling after 8 months of storage, indicating the poor stability of dispersion, great change in viscosity, poor heat storage and warming effects and low far infrared reflectivity. Furthermore, the fabric prepared with the finishing liquor exhibits a decrease by 6.28% in the heat storage and warming performance, and a decrease by 7.29% in the heat preservation effects after the fabric is washed 10 times.

[0056] These results demonstrate that different cross-linking agents, dispersing agents, and adhesives, as well as their combinations, when applied to the same proportion of heat storage, warming and heat preservation components, result in varying degrees of settling of the finishing liquor over time, and further causing significant changes in viscosity, dispersion, and dispersion stability of the finishing liquor. The dispersing agent ensures good dispersion of the finishing liquor and uniform distribution of effective components; the cross-linking agent and adhesive synergistically act on the effective components, maintaining stable dispersion and viscosity of the finishing liquor over a prolonged period of storage, and thereby locking the effective components in the finishing liquor. When applied to the fabric, more of these effective components are transferred to the fabric to achieve heat storage, warming and heat preservation effects. Furthermore, the synergistic effect of cross-linking agent, dispersing agent, and adhesive enhances adhesion of the effective components to the fabric surface, allowing the fabric to retain excellent heat storage, warming and heat preservation performance even after multiple washes.
